Cartagena's air quality benefits from its exceptional Colombian Caribbean coastal position on Cartagena Bay, with consistent Caribbean northeast trade winds providing reliable maritime ventilation. Vehicle traffic on surrounding roads and the refinery, port, and vehicle density corridor contribute local sources, while the outstanding Caribbean coastal exposure generally maintains Cartagena among Colombia's more moderately ventilated major Caribbean coastal industrial port cities throughout most of the year.

When is air pollution at its worst in Cartagena?
The biggest local contributors to pollution in Cartagena are traffic on the surrounding roads, heavy industrial and chemical processing, along with shipbuilding and port operations, particularly once dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Cartagena based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
